ClassNotFoundException: org.eclipse.jetty.util.component.AbstractLifeCycle running inside jetty
提问by erm410
I am having an issue running a servlet in jetty on Ubuntu 13.04. The server is installed using apt-getand started using sudo service jetty start. The app requires the class org.eclipse.jetty.util.component.AbstractLifeCyclebut I get a class not found error. Here is the stack trace:
我在 Ubuntu 13.04 上的 jetty 中运行 servlet 时遇到问题。使用 安装apt-get和启动服务器sudo service jetty start。该应用程序需要该类，org.eclipse.jetty.util.component.AbstractLifeCycle但我收到一个未找到类的错误。这是堆栈跟踪：

So far I have:
到目前为止，我有：
1) Examined the command used to start jetty to find the classpath using ps:
1）检查用于启动jetty的命令以使用ps查找类路径：
/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java -Djetty.home=/opt/jetty -Dovc.db_config=/home/ubuntu/ovc/data/ovc-repo/config/sql.properties -Dovc.repo_loc=/home/ubuntu/ovc/data/ovc-repo -cp /opt/jetty/lib/jetty-xml-9.0.4.v20130625.jar:/opt/jetty/lib/servlet-api-3.0.jar:/opt/jetty/lib/jetty-http-9.0.4.v20130625.jar:/opt/jetty/lib/jetty-continuation-9.0.4.v20130625.jar:/opt/jetty/lib/jetty-server-9.0.4.v20130625.jar:/opt/jetty/lib/jetty-security-9.0.4.v20130625.jar:/opt/jetty/lib/jetty-servlet-9.0.4.v20130625.jar:/opt/jetty/lib/jetty-webapp-9.0.4.v20130625.jar:/opt/jetty/lib/jetty-deploy-9.0.4.v20130625.jar:/opt/jetty/lib/jetty-jmx-9.0.4.v20130625.jar:/opt/jetty/lib/jsp/com.sun.el-2.2.0.v201303151357.jar:/opt/jetty/lib/jsp/javax.el-2.2.0.v201303151357.jar:/opt/jetty/lib/jsp/javax.servlet.jsp.jstl-1.2.0.v201105211821.jar:/opt/jetty/lib/jsp/javax.servlet.jsp-2.2.0.v201112011158.jar:/opt/jetty/lib/jsp/org.apache.jasper.glassfish-2.2.2.v201112011158.jar:/opt/jetty/lib/jsp/org.apache.taglibs.standard.glassfish-1.2.0.v201112081803.jar:/opt/jetty/lib/jsp/org.eclipse.jdt.core-3.8.2.v20130121.jar:/opt/jetty/resources:/opt/jetty/lib/websocket/websocket-api-9.0.4.v20130625.jar:/opt/jetty/lib/websocket/websocket-client-9.0.4.v20130625.jar:/opt/jetty/lib/websocket/websocket-common-9.0.4.v20130625.jar:/opt/jetty/lib/websocket/websocket-server-9.0.4.v20130625.jar:/opt/jetty/lib/websocket/websocket-servlet-9.0.4.v20130625.jar:/opt/jetty/lib/jetty-util-9.0.4.v20130625.jar:/opt/jetty/lib/jetty-io-9.0.4.v20130625.jar org.eclipse.jetty.xml.XmlConfiguration /tmp/start2620351902332669076.properties /opt/jetty/etc/jetty.xml /opt/jetty/etc/jetty-jmx.xml /opt/jetty/etc/jetty-http.xml /opt/jetty/etc/jetty-deploy.xml /opt/jetty/etc/jetty-logging.xml /opt/jetty/etc/jetty-started.xml
2) Inspected the jar that should contain the missing class:
2）检查应该包含缺少的类的jar：
~$ jar -tf /opt/jetty/lib/jetty-util-9.0.4.v20130625.jar | grep AbstractLife
org/eclipse/jetty/util/component/AbstractLifeCycle$AbstractLifeCycleListener.class
org/eclipse/jetty/util/component/AbstractLifeCycle.class
Can anyone give a suggestion as to what to check next, I am out of ideas? Thank you.
任何人都可以就接下来要检查的内容提出建议，我没有想法吗？谢谢你。

Put the jetty-util-9.0.4.v20130625.jarin your webapp's WEB-INF/lib/
把jetty-util-9.0.4.v20130625.jar你的webapp的WEB-INF/lib/
As you can see from the stacktrace, you are attempting to use a class found in jetty-util, from within a webapp.
正如您从堆栈跟踪中看到的那样，您正在尝试从 web 应用程序中使用在 jetty-util 中找到的类。
at org.eclipse.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:420)
This tells you that the webappneeds the class from jetty-util.
这告诉您web 应用程序需要来自 jetty-util 的类。
Because of webapp classloader isolation, and various rules within Jetty, the classes for org.eclipse.jetty.util.*are not provided by the server, and must be provided by the webapp's own WEB-INF/libdirectory.
由于 webapp 类加载器的隔离，以及Jetty 内部的各种规则，for 的类org.eclipse.jetty.util.*不是由服务器提供的，必须由 webapp 自己的WEB-INF/lib目录提供。

Put the following into your webapps/YOURWAR.xml, within the <Configure class="org.eclipse.jetty.webapp.WebAppContext">(the -in front of org.eclipse.jetty.util.is important):
将以下内容放入您的webapps/YOURWAR.xml, 内<Configure class="org.eclipse.jetty.webapp.WebAppContext">（-前面org.eclipse.jetty.util.很重要）：
<Call name="prependServerClass">
<Arg>-org.eclipse.jetty.util.</Arg>
</Call>
You need to prepend it, because the order is important and the last one which is added by default is org.eclipse.jetty.as documented on eclipse.org. So calling addServerClass would be a no-op, as org.eclipse.jetty.util.is already be excluded by org.eclipse.jetty..
您需要预先添加它，因为顺序很重要，并且默认添加的最后一个顺序org.eclipse.jetty.如eclipse.org 上所述。因此调用addServerClass将是一个空操作，因为org.eclipse.jetty.util.已经被排除在外org.eclipse.jetty.。

Joakim Erdfelt pointed the cause, in case anyone needs a snip of pom code, put this in pom file:
Joakim Erdfelt 指出了原因，如果有人需要一段 pom 代码，请将其放在 pom 文件中：
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-util</artifactId>
<version>9.3.6.v20151106</version>
</dependency>

In deployment environment, just make sure your server classpath has included the Spring jar library (e.g spring-2.5.6.jar).
在部署环境中，只需确保您的服务器类路径已包含 Spring jar 库（例如 spring-2.5.6.jar）。
For Spring3, ContextLoaderListener is moved to spring-web.jar, you can get the library from Maven central repository.
对于 Spring3，ContextLoaderListener 被移动到 spring-web.jar，您可以从 Maven 中央存储库中获取该库。

I got this when combining wiremock and DynamoDBLocal which both includes different versions of jetty. Excluding these dependencies in each of these and then explicitly having these in the pom with a specific version. However, seems org.eclipse.jetty.util.component.AbstractLifeCycle is only used in up to version 8.2.0.v20160908 (hence it does not solve it to have a newer version)
我在结合 wiremock 和 DynamoDBLocal 时得到了这个，它们都包含不同版本的码头。在其中的每一个中排除这些依赖项，然后在具有特定版本的 pom 中明确地包含这些依赖项。但是，似乎 org.eclipse.jetty.util.component.AbstractLifeCycle 仅用于最高版本 8.2.0.v20160908 （因此它不能解决它拥有更新版本）
